I know such thing like feedrate (F in G-code), but don't know any parameter
of velocity for combined moves. Does it exist? How is it called like and
where to find it?
Regarding Mach3 - I think I will be forced to try it with this machine too.

Greetings,
Well my machine is up an running nicely now, but now I want to make it go
faster!
My Z axis is about 10,000 lines per inch, so it uses up my available bandwidth
really fast. Right now I have the Z's max speed set to a mere 3 inches per sec.
My Y is 24 inches per sec, and X is 10

Is there anything I will need to order besides the Mesa's 4I30? How simple is
it to wire up? I assume the encoder signals go to the Mesa? How are the
Geckos wired? What does the parallel port connect to?
I have been using Mesa cards, but I am

Sorry, my mistake it was angular moves.
The valid params in the ini file are
The first thing to do is increase the allowable following error to a large
enough number you can experiment with the PID values. Then start tweaking P
and then D etc per the above protocol. You will be able to adjust for/in
either control loop mode.

That is why I think that 5i25 card would do much better - less
rewiring (actually You might get away with no rewiring at all) and
there also is price difference. Plug it straight in pci slot and
attach Your existing lpt cables to it. The only thing to do is sort
out the firmware - most
1 - is there some inherent incompatibility between Linux CNC and torque
mode servos?
2- is there some deeply buried config parameter that needs to be changed?
3- can somebody point us to a strategy specifically oriented to tuning
torque mode servos?
4- any other ideas?
Here are some

I don't understand what you're asking for. In LinuxCNC each axis

No, but a torque mode PID loop is also responsible for velocity control. This

1. I get it that this encoder.0.velocity is something that is reported in
rps if I have the scale set correctly, but what I am getting is an
extremely noisy reading for what looks like, and sounds like, a quite
